COMPANY NEWS: Facebook (FB) reported earnings and revenues last night that topped expectations, but its shares slid $1.78, or 1.84%, to $95.21 as the social network's growth in daily averages users fell a bit short of the consensus forecast and may have missed the high, "whisper" expectations for its report...
